www.DataSheet.co.kr Ordering number : ENA1864 Bi-CMOS LSI LV8740V Overview PWM Current Control Stepping Motor Driver The LV8740V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepping motors used in office equipment and amusement applications. Features • Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated. • On resistance (upper side : 0.3Ω ; lower side : 0.2Ω ; total of upper and lower : 0.5Ω ; Ta = 25°C, IO = 2.
